Kaedah pembenaman data baru untuk imej berkualiti tinggi, cth, imej dengan nisbah isyarat-ke-bunyi puncak lebih baik daripada 60 [dB] dicadangkan dalam kertas ini. Kaedah yang dicadangkan dengan tepat menghasilkan imej tera air yang diingini dan berkualiti tinggi untuk sebarang imej. Untuk melakukan ini, kaedah ini mengambil kira panjang perkataan terhingga bagi nilai kecerahan piksel, iaitu, kedua-dua ralat pengkuantitian dan had julat kecerahan. Kaedah yang dicadangkan membenamkan jujukan tera air, dimodulasi oleh mekanisme skema spektrum sebaran, ke dalam nilai dc imej dalam domain spatial. Dengan menggunakan teknologi spektrum sebaran serta membenamkan tera air ke dalam nilai dc, kaedah ini menjamin kualiti imej yang tinggi dan, pada masa yang sama, memberikan toleransi JPEG yang mencukupi.

Abstract: A novel data embedding method for high-quality images, e.g., an image with a peak signal-to-noise ratio of better than 60 [dB] is proposed in this paper. The proposed method precisely generates a watermarked image of the desired and high quality for any images. To do this, this method considers the finite word-length of a luminance value of pixels, i.e., both quantization errors and the range limitation of luminance. The proposed method embeds a watermark sequence, modulated by the mechanism of a spread spectrum scheme, into the dc values of an image in the spatial domain. By employing spread spectrum technology as well as embedding a watermark into the dc values, this method guarantees the high image quality and, simultaneously, provides adequate JPEG tolerance.
